Imaging
- Abdominal ultrasound focussing on the pelvis, ovaries, para-aortal
lymph nodes (right ovarian tumor) and renal lymph nodes (left ovarian
tumor) [Level II, Grade A].
- Abdominal and pelvic MRI [Level IV, Grade A].
- Chest X-ray or low-dose chest CT. Comment: OSCST extremely rarely
metastasize at distant sites, almost never beyond the diaphragm. Most
metastases occur within the abdominal cavity, leading to peritoneal
tumor spread, or to the locoregional pelvic or retroperitoneal lymph
nodes [Level IV, Grade B].8, 21–23
